Title: Semiconductor light emitting device
Inventor: YOSHIDA KAZUTOMI
IPC: H01L33/30
Filed: 1987-11-06
Abstract: PURPOSE:To obtain a semiconductor light emitting device wherein operating voltage is low and heat generation is little, by arranging an intermediate electrode having an area equal to a mesa area, between the highest layer of a mesa part and the aperture part of SiO2, and reducing the ohmic resistance between an electrode and crystal. CONSTITUTION:An intermediate electrode 8a having an area equal to the upper part area of a mesa is arranged, between an aperture 12 of SiO2 and a contact layer 5. Although an aperture 11 is small, the P-electrode 8b and the P-InGaAsP contact layer 5 has a maximum contact area. An ohmic resistance between the electrode 8a and the contact layer 5 becomes small in the case of the same diameter of mesa, as compared with conventional mesa type light emitting diodes. The ohmic resistance between the electrode 8a and a P-electrode 8b can be made almost equal to zero, by using the same electrode material. Thereby obtaining a semiconductor light emitting device wherein operating voltage is low and heat generation is small.

Filed: 1991-10-28
Abstract: PURPOSE:To reduce the occurrence of a measurement error resulting from an unbalanced voltage by making the continuity of a current to a coil zero at regular periods and, at the same time, correcting the voltage detected by means of a Hall element after comparing the voltage with a voltage detected by means of the element when the current continuity to the coil is zero. CONSTITUTION:A coil 2 is provided with a switch 1 for by-passing the coil 2 and the turning on/off of the switch 1 is controlled by a pulse generated from a pulse generator 10. Firstly, the switch 1 is closed by the signal of the generator 10 so that no current can flow to the coil 2. When a switch 7 is switched to a sample hold circuit 8 side at the same timing, the circuit 8 can hold an unbalanced voltage. Thereafter, when the switch 1 is opened by the signal of the generator 10 and the switch 7 is switched to the (+) input side of a differential amplifier 9, a detecting current flows to the coil 2. As a result, the output of this current detector does not contain any unbalanced voltage and the detector outputs detected power which does not contain any error caused by the fluctuation of the unbalanced voltage.

Abstract: PURPOSE:To prevent the transmission and the reception of terminal equipment from being given bad influence 6 by sending destructive data to be sent to the terminal equipment after converting it into a waiting pattern to secure a waiting state till the recovery of synchronization. CONSTITUTION:A pair of the terminal equipments 20A, 20B are provided with means 4, 5, 7, 12 to 14 to transmit and receive the destructive data due to a non-synchronized state by substituting the waiting pattern to be kept in the waiting state till the recovery of the synchronization for it at the time of the non-synchronization of data communication between a pair of the terminal equipments. Here, at the time of the non-synchronization, the waiting pattern is sent previously instead of the destructive data to be sent to the terminal equipment 20A, 20B, and the data communication is started again after the synchronization is secured. Thus, the influence of the disorder of the transmission and the reception of a terminal equipment side at the time of the non- synchronization can be suppressed to minimum.
